When You Can't Afford to Lose Detail
PNG compresses without throwing anything away. Convert a page of contract text to JPG and you get faint smudging around the letterforms; convert it to PNG and every character is exactly as sharp as it was in the PDF. For anything with text, thin rules, or fine chart lines, that difference is visible at normal zoom.
PNG also carries an alpha channel, so transparency survives the conversion instead of being flattened onto white.
The tradeoff is size — PNG files run several times larger than the JPG of the same page, and there's no quality slider to trade away because there's no lossy step to tune. What you can change is resolution: 72, 150, or 300 DPI. Everything happens in the browser, and multi-page documents come back as a ZIP.
Converting a PDF to PNG
- Drop the PDF onto the page
- Choose the resolution you need
- Click Start conversion
- Download the pages individually or as a ZIP
Worth Knowing

- Three resolutions: 72, 150, and 300 DPI
- Transparency is preserved rather than flattened
- Convert several PDFs in one session
- Page thumbnails before you download anything
- ZIP download for multi-page documents
- Free, no sign-up
Where It Matters
Contracts and specs
Documents where someone will zoom in to read a clause or a tolerance. JPG artifacts show up exactly there.
Charts pulled into a report
Thin axis lines and small labels are the first thing lossy compression ruins. PNG keeps them clean.
Print and design work
300 DPI PNG is the format a designer will ask you for when a page has to be placed into layout.
Why PDF to PNG Converter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your PDF files to any server — everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere — processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk — no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes PDF files in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No PDF files remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your PDF files externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your PDF files are made. This can also serve as documentation for your IT security team.
Before You Convert
Is the file uploaded anywhere?
No. Rendering and encoding both happen inside your browser. There is no server copy of the document at any point.
PNG or JPG — which do I actually want?
PNG if the page is mostly text, tables, or diagrams. JPG if it's mostly photographs and you care about file size. If you're unsure, convert one page each way and look at them side by side at 100%.
Why are the files so much bigger?
Because nothing is being discarded. Lossless compression can only remove redundancy, not detail, so a PNG page routinely lands several times larger than the JPG. That's the deal you're making in exchange for sharp text.
Which DPI?
72 for screens, 150 for reading and presenting, 300 for print. Higher settings multiply both the rendering time and the output size.
Can it open password-protected PDFs?
No. Remove the password first, then convert.
